bpftrace: fix the runtime ptest errors

bpftrace/bpftrace#2935 changed the test scripts,
then the runtime ptest got the following errors:
| KeyError: 'BPFTRACE_AOT_RUNTIME_TEST_EXECUTABLE'
| Output: /bin/sh: line 1: /usr/bin/: Is a directory\n
The changes in run-ptest is to solve these problems.

After fixing the previously mentioned problems,
we got the the following errors while running the runtime ptest:
| error: <unknown>:0:0: in function BEGIN i64 (ptr): 0x56056cec80f0: i64 = GlobalAddress<ptr @__atomic_compare_exchange> 0 too many arguments
The new patch in the bb file is to solve this problem.

+Subject: [PATCH] use 64bit alignment for map counter atomic add
+
+For an atomic inc of a map counter (ringbuf loss counter), generate
+IR with 64bit alignment. This is more correct, and will avoid problems
+with upcoming LLVM versions, as they will emit a function call for
+a potentially unaligned atomicrmw. This will lead to an error like this:
+
+error: <unknown>:0:0: in function BEGIN i64 (ptr): t15: i64 = GlobalAddress<ptr @__atomic_compare_exchange> 0 too many arguments
